“…In particular, feature extraction, registration and simplification are the most important visual processing tools recently worked upon in the rapid prototyping community. In (Mérigit et al, 2011;Novatnack and Nishino, 2007;Zhao et al, 2010;Zheng et al, 2009), normal estimation and corner extraction over unorganized point sets are algorithmically defined in order to perform UPS registration (Lin and He, 2011;Myronenko and Song, 2010;Rusu et al, 2008) or simplification (Sareen et al, 2009;Song et al, 2009;Xiao and Huang, 2010) for instance. A lot of works also deal with surface segmentation issues like in (Douillard et al, 2010;Huang & Menq, 2001;Jagannathan & Miller, 2007;Rabbani et al, 2006).…”
